• Power coefficient of resistance (PCR) “ΔR due
to self heating”: 5 ppm at rated rower
• Electrostatic discharge (ESD) above 25 000 V
• Resistance range: 5 Ω to 30 kΩ
Any value at any tolerance available with resistance range
The Z202 is a miniaturized version of the now famous Z201. It is
made with a Bulk Metal® Z-Foil element so it retains all of the
inherent performance of Z-Foil resistors.
(for higher or lower values, please contact us)
• Power rating: 0.25 W at + 70 °C; 0.125 W at + 125 °C
• Load life stability: 0.01 % maximum ΔR at + 70 °C at
Rated power for 2000 h
• Non inductive, non capacitive design
• Current noise: - 40 dB
• Thermal EMF: < 0.1 µV/°C
• Voltage coefficient: < 0.1 ppm/V
The Z-Foil technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
Designers can now guarantee a high degree of stability and
accuracy in fixed-resistor applications using solutions based
on Vishay’s revolutionary Z-Foil technology.
• Non inductive: < 0.08 µH
• Non hot spot design
• Maximum working voltage: 250 V
• Terminal finishes available: lead (Pb)-free
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
